I was playing around with the calibration but never got it working to my liking. I couldn't get rid of those random 2-4 pixel jumps when aming down sight with a sniper rifle. I'm using Roccan Kone XTD Optical mouse with max 6400 dpi. I copied over your config and in-game settings and must say it is working great now. So thank you mate If you ever update it and make it work even better be sure to post it here

I have just finished the ultimate config for BF1! I've spent a lot of hours and several days working on and fine tuning this one. My mouse is so baby smooth while Sniping/Aiming down the sight. No jitters or jumping around while trying to target a distant enemy with the scope. Feels just like I'm playing a PC game! My keyboard layout is similar to the way I used to play MOHAA on the PC. Hold shift for sprint always my favorite! I have two extra thumb buttons on the side of my mouse so some of you may need to move around a couple of the keyboard buttons. Left and Right D-pad are my mouse thumb buttons. When you hover your pointer over the left & right D-pad on FPSConfig my mouse thumb buttons show up as Button_X4 and Button_X3. Find out what DPI your mouse is and convert the Mouse DPI on the FPSConfig screen to match your mouseno exceptions! My mouse DPI is 10,000, and I am using my Razer Death Adder Chroma!

Get to in game options and change the stick dead zone to 0, also set ALL sensitivity options in game to maximum. There are a lot of sensitivity options so make sure you explore and get them all.. coefficient setting should be 300% maxed. Download my config below and try it out for yourself! If you need to change the sensitivity to suite you better then you should only adjust the Sens. values for Hip Fire and ADS via GIMX only. Don't try to adjust your sensitivity with in game settings or by moving your DPI around. My config has a value of 10.00 for Hip Fire and 6.25 for ADS.

I will be working on a second profile in this config that can be swapped too with the touch of a designated hotkey for vehicles and planes. This way I can create what works best for say driving a tank and flying and set it up so that you can switch to those settings and back to infantry soldier settings on the fly with the press of a button! I've been using Gimx for a very long time. There is so much to learn about it. I love Gimx!

I am a GIMX beginner and just finished building my first DIY-USB adapter last weekend.

I downloaded your config, made some adjustements and have to admit: this feels very good!
Previouly I used a HORI TAC but I never stopped searching for options as I don't like the mouse translation and limited configuration features.
Yes, there is the XIM4 option but to expensive for me.

@MATLO:
What is the key difference between a GIMX solution and a XIM4 from your point of view? (next to the price! )
Do you know if the XIM4 uses similar/identical HW components?
I am asking this because I want to know if it will be theoretically possible to get a similar 1:1 mouse translation in GIMX as with a XIM4 like this is often stated in internet forums and youtube videos?

Anyway: Congratulations to you for this excellent project! 5 stars!

Even though this is a very good solution I am still having some issues with the mouse behaviour: as faster I move the mouse as "slower" the motion is.
Of course, I did the mouse calibration procedure, tried out different values - without success. (see config below)
